Bulk Of Cream no Guide.

Bulk of Cream no Guide.
DaiTymen should not aim to furnish
cream that will yield the largest
amount of oil nor ON the other hand
should they aim to so raise and skim
their cream that there will be the
greatest bulk, but the latter object
would be less mistake than the form
er. Ii is no credit TO farmer, to his
! cows. to his feed or to his manner of
handling cream that his test at the
creamery shows "A large amount of oil.
On the contrary the creamery-m
usually gives his collectors instructions
to take special notice as to the quality
of the cream that tests the highest.
The dairyman's first object should be
to get the proper quality of cream and
it will not be necessary to worry
about the quantity, for if the milk
is set Immediately upon being drawn
in cold water and kept cold the
cream will all come TO the surface
aud, so far as the setting is con-
cerned, the quality will be there.
The following article from the u.
S. Dairyman on this subject is
MOIln a CdIclul LtduluR.
1t was once thought that cream was
cream, and that there was no difference
in quality; and some of our expert
mentors continue to work on this as
sumption. 1t is great mistake.
The bulk of cream is no guide what
ever for determining the amount of fat
in milk, or even for aproximating the
amount. 1t has been shown again and
again, that the variation in the butter
valuation of cream is in some instances
as high as 200 per cent. Then why
should anybody at this late day, be
talking about the amount of cream to
he obtained from this and that cows
milk, or by this or that method of
separating the cream from the milk?
Yet it is done in the name of science!
So much depends, not only on the
quality of the milk, but on the method
of separation, the time occupied in
doing it, the temperature at which the
cream is raised, and the amount of milk
taken with the cream in skimming.
The condition of the cow, the quality
of the feed, the length of time from
calving, and the individual character
istics of the cow, affect the quality of
the milk, and cOrrespondingly the quail
ity of the cream. If the cow is in
poor flesh, and half starved, the butter
globules are poor in fat. On the con-
Jrary, if the COW is in good condition,
aud abundantly fed with good, nutri-
tious food, the glObules will be rich in
fat aud fine favored.
Cream raised at low temperature
is more frothy and bulky than cream
raised more slowly at higher temper

longer the cream stands after raising.
the more solid it gets, and the more
fat q cubic inch of il contains. Fur
thermOre, the mode of Swimming may
include more or less milk with the
cream. So great is the variation that
it has been repeatedly found that
given bulk of cream-say liz cubic
inches supposed to yield pound of
butter, in one instance would yield only
half a pound, and in another a pound
and half. And, some cows always
give milk poor in cream and poor in
quality. We believe the two delicien-
cies generally go together.
1t is still more absurd to talk about
the amount of cream obtained by deep
or shallow setting, ds compared with
the amount obtained by centrifugal
separation. We have not only the re-
lations just spoken of, but how are we
to determine how much milk the sep
arator takes with the creaml 1t may
take very little or good deal, just as

by the separator is very different

for the purpose of obtaining definite.
results.
The amount of butter churned from
a given amount of cream or milk is a
much better guide to its quality;
The question of which is the best
breed for this or that dairy purpose can
only be answered in general way, and
that answer may be cOntradicted by the
first individual test.
We hope to see the day arrive, and
that speedily, when scientific expert
ments will cease to rely upon the bulk
of cream as guide to the amount of
fat given quantity of milk contains,
or the per cent. it contains, or as any
indication of the relative value of
either breeds or individuals. All reas-
oning and conclusion reached on such
basis are utterly fallacious and USE
